Why is my red brick turning white?
A: If you’re seeing a white, powdery discoloration on the brick, then it’s called efflorescence. This is the common result of mineral salts leaching out of the brick. The good news is that it’s not harmful to the brick. To remove the efflorescence, mix a heavily diluted solution of water and muriatic acid.
Why have my bricks turned white?
Efflorescence is a crystaline, salty deposit that occurs on the surfaces of bricks, concrete and other masonry products. It is white, sometimes a brilliant white or an off white colour. When salt loaded water reaches the surface of the brick, air evaporates the water, leaving the salt behind.
Why do my bricks have white on them?
Efflorescence is a crystalline deposit of salts that can form when water is present in or on brick, concrete, stone, stucco or other building surfaces. It has a white or greyish tint and consists of salt deposits that remain on the surface after water evaporates.
Does vinegar remove efflorescence?
Vinegar and water solution—Efflorescence can be removed by using a dilute solution of household white vinegar and water. A vinegar and water solution is relatively inexpensive, non-toxic, and easy to obtain, mix and apply. For most cases of efflorescence a 25% solution works well.
What is the best way to remove efflorescence?
The best time for removing efflorescence is when the weather is warm and dry.
- Stiff brush. On some smooth surfaces, you may be able to use a stiff brush.
- Water rinse. On other surfaces, rinsing with a garden sprayer or pressure washer can dissolve efflorescence, allowing it to run off.
- Chemical cleaning.

Will cleaning efflorescence from brick stop it from getting worse?
Cleaning efflorescence from brick will not cure the problem meaning it only cleans the surface of the brick but will not stop efflorescence prone bricks from re-depositing more salts on the surface.
How do you get vinegar out of brick?
